Crystal coherence length
In physics, coherence length is the propagation distance over which a coherent wave (e.g. an electromagnetic wave) maintains a specified degree of coherence. Wave interference is strong when the paths taken by all of the interfering waves differ by less than the coherence length. A wave with a longer … See more In radio-band systems, the coherence length is approximated by $${\displaystyle L={\frac {c}{\,n\,\mathrm {\Delta } f\,}}\approx {\frac {\lambda ^{2}}{\,n\,\mathrm {\Delta } \lambda \,}}~,}$$ See more • Physics portal • Coherence time • Superconducting coherence length • Spatial coherence See more Multimode helium–neon lasers have a typical coherence length on the order of centimeters, while the coherence length of longitudinally single … See more Tolansky's An introduction to Interferometry has a chapter on sources which quotes a line width of around 0.052 angstroms for each of the Sodium D lines in an uncooled low … See more WebNov 12, 2010 · The crystalline coherence length, a measure of the out-of-plane SG size λ ⊥ [20], was determined by XRD θ/2θ scans through the analysis of the preferred orientation peak (Au (1 1 1)) with...
